154398 Which of the following statement related to hysteresis loop is incorrect?

1 The curve of $\mathrm{B}$ against $\mathrm{H}$ for a ferromagnetic material is called hysteresis loop
2 The area of B-H curve is a measure of power dissipated per cycle per unit area of the specimen
3 Coercitivity is a measure of the magnetic field required to destroy the residual magnetism of ferromagnetic material
4 The retentivity of a specimen is the measure of magnetic field remaining in the specimen when the magnetising field is removed
